In April 2015, using enclosed static opaque chamber-GC techniques, the short-term effects of nitrogen and sulfate addition on the CH
4
and CO
2
emissions were measured in the
Cyperus malaccensis
marsh in the high tidal flat of the Minjiang River estuary, and the key factors controlling the variation of CH
4
and CO
2
were examined. The influences of nitrogen and sulfate addition on the CH
4
and CO
2
emissions were different in different time scales. CH
4
emission increased significantly under the NH

Cl (NH) and NH

SO

(NS) additions (
P

2
emission increased significantly with NS addition (
P
<0.05), but CH
4
and CO
2
emissions demonstrated an obvious fluctuation pattern with
KNO

(NO) and K
2
SO
4
(S) additions. Compared with the control (CK), average CH
4
emissions increased by 286.36% and 122.73%, respectively, in the NH and NS addition treatments, average CO
2
emissions increased by 39.92% and 34.24%, respectively, with the NH and NS additions treatments. The nitrogen and sulfate addition changed the temporal variation of CH
4
and CO
2
emissions from the
C. malaccensis
wetlands in growing season. Significant correlations were found among CO

emissions, and soil temperature, electrical conductivity (EC),
